Nuevas tendencias en el tratamiento del dolor postoperatorio en cirugía general y digestiva

The correct application of multimodal analgesia appropriate to the pain intensity, the characteristics of the surgery and the hospitalisation scheme provide the key to improving the management of postoperative pain, which is currently still under treated. In highly complex surgeries the best benefit is obtained by combining systemic analgesic drugs with regional analgesia techniques.Epidural analgesia, not only provides an excellent quality of analgesia, but can prevent complications and reduce postoperative morbidity. Recently, peripheral blocks and parietal infiltration techniques, with or without catheter, have gained prominence in the postoperative analgesia of haemorrhoids and hernia repair. All these analgesic techniques are integrated into the concept of early postoperative rehabilitation and pursue the objective of minimising the side effects associated with the treatment and facilitate the functional recovery of the patient. In addition, proper postoperative pain management, not only increases the quality of in-patient care but is also a factor to consider in the development of chronic post-surgical pain, where the impact is significant and impairs the quality of life of the patients.     

Relación entre concentración intraoperatoria de parathormona y evolución postoperatoria del hiperparatiroidismo primario

Introduction

The relationship between the intra-operative concentration of parathyroid hormone (IOPTH) and the long-term outcome of patients intervened due to primary hyperparathyroidism (PHPT).

Patients and methods

A prospective observational study was performed with 120 patients. Three determinations were made of PTH in blood: baseline, when the diseases gland was located, and 10 minutes after its extirpation. The calcium, PTH and vitamin D (25-OH-D3) levels were measured during follow up.

Results

A decrease in IOPTH > 50% was observed in 96 (80%) patients, and the post-extirpation value returned to the normal range (Group I), in 18 (15%) a decrease of > 50% but the final value remained higher than normal (Group II) and in 6 (5%) the decrease was < 50% (Group III). Persistent PHPT was detected during follow up in 6 patients (5%): one in Group I (1%), 3 (16.7%) in II and 2 (33.3%) in group III (P < .001). The risk of persistent PHPT was higher in Group II (odds ratio: 19; 95% CI: 1.85-194) and in Group III (odds ratio: 47; 95% CI: 3.53-639). There were no cases of recurrent PHPT. A normal calcium with an increased PTH was detected in 20 patients of Group I (20.8%), 11 (61.1%) in II and 3 (50%) in III (P < .001). These patients had a lower concentration of post-operative vitamin D (17 ng/ml, range: 24; compared to 28 ng/ml, range: 21) (P = .008) and higher frequency of hypovitaminosis D (70.6% compared to 26.2%) (P>.001).

Conclusion

The risk of persistent PHPT is higher when the IOPTH decreases more than 50% but still remains high.
